'Denounce' in the Bible

I denounce to you this day, that you shall surely perish; you shall not prolong your days in the land, where you pass over the Jordan to go in to possess it.

For I have heard the defaming of many, terror on every side. Denounce, and we will denounce him, [say] all my familiar friends, those who watch for my fall; perhaps he will be persuaded, and we shall prevail against him, and we shall take our revenge on him.
